It is well ,known that heretofore in the con-- stant operation of gears, particularly when employed to drive 'a heavy load or for great speed, they'become worn and in some cases 0' of metal drop into the lubricating-oil in the casing and amended up therewith between the gears and into the bearings, resultingin a short time in so cutting out the-teeth of the gears and the, bearings that the gears will mesh loosely, and consequently their motion will be jerky and that the hearings will become worn, thus shortening the life of usefulness of said parts and reguiring new parts to be frequently substitute therefor. It is therefore the object of this invention to obviate this objectionable feature by roviding magnetic means within the casin for collecting the metalparticles from the 011 as they falLtherein and retaining them, so that they cannot be carried up betw en the gears or into the bearings, thereby greatly lengthenin th'e'life of sa1d parts. A urther object of this invention is to'pro- 3 5 videmeans of'the character set forth embody I 3 ing advantages inpoint of effectiveness, easy attachment, simphcity, and'expensiveness of construction.

uid lubricant, and 2 a system of sliding gears supported therein. To the interior surface of the casing, preferably at the bottom to take advantage of the specific gravity of the metal particles, 1 'secure a ma etic bar 3 by referabd y by bolts 4, extendingthrough ho es 5 in said bar and 5 5 holes 6 in the casing and having nuts 7 on their ends.

It will be understood from the fore oing description, considered in connection wit the accompanyin drawings, that when the particles of metafworn or broken from the gearsfall'into the lubricating liquid they are attracted by the magnetic bar and adhere thereto, thus being prevented from being carried up between the gears or into the bea'rm s, and that when the bar becomes covered wit these metal particles they can easilyandreadily be removed by scraping or in any other manner desired. Having now described my invention, what 0 I claim as new, and desire to secure by Let- I ters Patent, is-

1. The combination with a gear-casing, of a magnetic b'ar. therein, substantially as described. g 7 2. The combination with a gear-casin of a magnetic bar secured therein, substantially 3. The combination with a gear-casing, of

;a magnetic bar therein and means for remov- 3Q abl securing said bar place, substantially as escribed.

4. Thecombinati0n with a gear-casing of means therein for attracting metal particles, substantially as described. 5

5. The combination with a gear-casing, of

alma etic bar therein, bolts passing through said ar and casing and nuts'on said-bolts, substantially as described.
